We look at the division of 19902696 by 599 
The aim is to understand the frequency of 599 in 19902696.

On to step 1:
1 divided by 599 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 599

Moving on to step 2:
599 can be fit into 19 0 times, resulting in a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 599

On to step 3:
599 goes into 199 0 times with a remainder of 199.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 199 to get 199.
Grab the next digit (0) from the dividend, add it to 199, then carry on: 1990 / 599

On to step 4:
When dividing 1990 by 599, we get 3 with a remainder of 193.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 193 after subtracting 1797 from 1990.
Append the next digit (2) from the dividend to 193 and continue with: 1932 / 599

On to step 5:
599 can be fit into 1932 3 times, resulting in a remainder of 135.
Write down 3 as next digit of the result. 
Result so far: 33.0
The remainder is 135 after subtracting 1797 from 1932.
Take the next digit (6) from the dividend and append it to 135, then repeat: 1356 / 599

Moving on to step 6:
599 can be fit into 1356 2 times, resulting in a remainder of 158.
The next digit of our result is 2. 
Result so far: 332.0
If we take 1198 away from 1356, we end up with 158.
Append the next digit (9) from the dividend to 158 and continue with: 1589 / 599

On to step 7:
599 goes into 1589 2 times with a remainder of 391.
Put 2 as the next digit of the answer. 
Result so far: 3322.0
Deduct 1198 from 1589 and we're left with 391.
Include the next digit (6) from the dividend after 391, then repeat: 3916 / 599

Advancing to step 8:
599 can be fit into 3916 6 times, resulting in a remainder of 322.
Put 6 as the next digit of the answer. 
Result so far: 33226.0
If we subtract 3594 from 3916, we get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 9:
599 goes into 3220 5 times with a remainder of 225.
The next digit of our result is 5. 
Result so far: 33226.5
Subtract 2995 from 3220 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 10:
The number 599 fits into 2250 3 times, leaving a remainder of 453.
The next digit of our result is 3. 
Result so far: 33226.53
Deduct 1797 from 2250 and we're left with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Going ahead to step 11:
599 can be fit into 4530 7 times, resulting in a remainder of 337.
Record the quotient 7 as the next digit in the result. 
Result so far: 33226.537
If we take 4193 away from 4530, we end up with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Going ahead to step 12:
599 can be fit into 3370 5 times, resulting in a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 33226.5375
Subtracting 2995 from 3370 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 13:
599 can be fit into 3750 6 times, resulting in a remainder of 156.
Put 6 as the next digit of the answer. 
Result so far: 33226.53756
Deduct 3594 from 3750 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 14:
599 can be fit into 1560 2 times, resulting in a remainder of 362.
The next digit of our result is 2. 
Result so far: 33226.537562
Deduct 1198 from 1560 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 15:
The number 599 fits into 3620 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 33226.5375626
If we subtract 3594 from 3620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 16:
When dividing 260 by 599, we get 0 with a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 33226.5375626
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

After the division, we end up with 33226.5375626 and a remainder of 2.6e-07.
